This picture is of the slopes surrounding the town of
Manarola. The hills are home to a terraced vineyard. We hiked through this
vineyard as we made our way from Manarola to Riomaggiore. Because of the steep
slope of the hill, the vineyard would not be able to exist without the use of
terracing. The terracing of the hills mitigates runoff and soil erosion and
makes the vineyard more accessible to workers. Terraces can be found throughout
Italy due to the hilly terrain that is so prevalent in this country.
Although terracing facilitates agriculture on steeply graded
land, it is not without its challenges. One such challenge is irrigation. Note
the black tube in the far right of the picture. This appeared to be a part of
an irrigation system for the vineyard. The tube ran all the way up to the top
of the hill (about a 30 minute hike). This system was certainly difficult to
install, and its maintenance is made less convenient by the precarious slope on
which it is situated. And, depending on the local water pressure, mechanical
work might need to be added to cause the water to reach the top of the slope.
Another challenge that comes with terraced agriculture is
the lack of automation. Terracing precludes machinery from being used to
harvest. Instead, fruits must be harvested by hand. Manual harvesting is less
efficient and, in the case of olives, more dangerous than harvesting with
machinery. Terracing is not without its drawbacks, but it makes agriculture
possible in areas that would not yield crops without it.
